How do I receive airdrop items?

I'm curious about how to effectively receive airdrop items in the world of cryptocurrency. Could you please explain the process in a step-by-step manner? Firstly, are there specific requirements I need to fulfill, such as holding a certain amount of a particular coin or token? Secondly, how do I stay updated on upcoming airdrops? Do I need to subscribe to specific newsletters or join specific communities? Lastly, once an airdrop is announced, what actions do I need to take to ensure I receive the tokens? I'd appreciate a detailed yet concise explanation as I'm still relatively new to this aspect of cryptocurrency.
